I do not understand the process/steps to do this. ​
VARVARA [1.3K]

Answer:

Step-by-step explanation:

Remark

An angle bisector sets up a triangle ratio that looks like the following proportion.

3x - 3               5x

======   =      ======             Cross multiply

24                     44    

44*(3x-3) = 24*5x                 Remove the brackets on the left

132x - 132 = 24*5x               Combine the right side

132x - 132 = 120x                 Add 132 to both sides

132x = 120x + 132                Subtract 120x from both sides

132x- 120x = 132                  Combine

12x = 132                              Divide by 12

x = 11

Eleanor and Max used two rectangular pieces of plywood, placed end-to-end, to make a long rectangular stage for the school play.
Flauer [41]

Answer:the width of plywood = 6.25 feet wide or  6 1/4 feet wide

Step-by-step explanation:

Step 1

Area of  a rectangular plywood = length x width

Area of Ist Plywood= 7 x w

Area of 2nd  Plywood= 61/2 x w=6.5 xw

But Total Arae of trhe two Plywoods are = 84 3/8 square feet.

Therefore Our equation to solve the problem becomes

Area of Ist Plywood + Area of 2nd  Plywood =84 3/8 square feet.

7w + 6.5w =  84 3/8

13.5w= 84 3/8

w =  84 3/8/13.5

675/8  / 13.5

w=6.25

Therefore the width of plywood = 6.25 feet wide or 6 1/4 feet.
